This paper presents the design and implementation of 2x1microstriptriangular patch antenna array using microstrip line feed for x-band. The design of microstrip patch antenna array is realized using Quarter wavelength transformer. The operating frequency of microstrip patch antenna array isin the range of 8GHz-12GHz is chosen. Each antenna operates in its own operating resonant frequency. The array of two by two microstrip triangular patch antennas with edge feed technique were designed, simulated and measured with the IE3D Zeland software. The simulation and measurement results are able to operate in X-band. The array antenna is designed on GML 1000 having dielectric constant (Ɛr) of 3.2 and thickness of 0.762mm, respectively. Further, the result shows that the proposed array antenna with triangular shaped patch has the gain of 7.7 dB, directivity of 10.2 dBi and the return loss of -15.05 dB at 9.7 GHz.
